Removal Of Tonsils And Adenoids Associated With Ongoing Benefits For Children With Breathing Problems During Sleep
Two and a half years after children with sleep-related breathing disorders had surgery to remove their tonsils and adenoids (glands in the back of the throat), they appear to sleep better than they did before the procedure but not as well as they did six months after, according to a report in the July issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives journals. Initial improvements in their behavior were maintained except when measured by an index of attention-deficit/hyperactivity disorder (ADHD) symptoms.

Mimic-effect: Video Therapy Helps Stroke Patients
Video therapy, through which certain brain sectors are activated by visual stimuli, can help restore movement in patients suffering stroke-induced paralysis. That conclusion is part of a current study that researchers from Konstanz, Freiburg and Magdeburg, Germany, are presenting at the current meeting of the European Neurological Society (ENS) in Milan, Italy. This major meeting in European neurology gathers more than 2,900 experts from all over the world. The role played by brain mirror neurons is central in this context.

Brain Activity Stablilized By Dynamic Molecular Mechanism

In the brain, many types of synaptic proteins are spatio-temporally regulated to maintain synaptic activity at a constant level. Here, the Japanese research group led by Professor Masaki Fukata, Drs. Yuko Fukata and Jun Noritake in National Institute for Physiological Sciences, Japan, found that two types of palmitoylating enzymes finely-tune the location and function of a major synaptic protein, PSD-95, in different ways. They also found that this mechanism contributes to keeping synaptic activity stable when synaptic activity dynamically changes. The Japan Science and Technology Agency (JST) supported this study. They report the finding in Journal of Cell Biology published on July 13, 2009. The research group focused on two types of palmitoylating enzymes, DHHC2 and DHHC3. Protein palmitoylation, the most common lipid modification with the 16-carbon fatty acid palmitate, provides an important mechanism for regulating synaptic proteins in neurons. Here, the research group found that DHHC3 is located in the cell body of neurons to palmitoylate newly synthesized synaptic proteins such as PSD-95, and move out them into dendrites of neurons. In contrast, DHHC2 are located mainly in dendrites of neurons. Dendritically localized DHHC2 mediates dynamic palmitoylation of PSD-95 at synapses upon extracellular signals. When synaptic activity decreases, DHHC2 translocates to the synaptic site to facilitate palmitoylation of synaptic proteins to keep synaptic activity at a constant level. "We have already found 23 types of palmitoylating enzymes. Our finding suggests that individual palmitoylating enzymes have distinct functions in neurons. Some of palmitoylating enzymes are known to be differently related to neurological disorders such as mental retardation, schizophrenia and Huntington"s disease. Therefore, this palmitoylating enzyme family may represent exciting therapeutic targets", said Professor Fukata. Masaki Fukata National Institute for Physiological Sciences
